Cognitive display device for virtual correction of consistent character differences in augmented or virtual reality

ABSTRACT

A method, computer program product, and visual display apparatus include a processor(s) obtaining data indicating that a user wearing the apparatus (which included an image capture device, and a projection device, communicatively coupled to the processor(s)), perceives displayed text with consistent character differences. The processor(s) obtains, from the image capture device, an image of a visual display within a visual range of the image capture device; the image includes textual elements. Based on the data, the processor(s) transforms the image into the new image that includes the textual elements with pre-defined character substitutions, based on the consistent character differences. The processor(s) displays, via the projection device, the new image, to the user, wherein based on viewing the new image, the user views the textual elements without the consistent character differences.

BACKGROUND

Various issues can result in a situation where an individual is unableto read displayed text correctly. For example, experiencing challengessuch as dyslexia and dysgraphia, may prevent individuals fromrecognizing written characters and words, as they would appear in theabsence of these challenges.

DETAILED DESCRIPTION

The accompanying figures, in which like reference numerals refer toidentical or functionally similar elements throughout the separate viewsand which are incorporated in and form a part of the specification,further illustrate the present invention and, together with the detaileddescription of the invention, serve to explain the principles of thepresent invention. As understood by one of skill in the art, theaccompanying figures are provided for ease of understanding andillustrate aspects of certain embodiments of the present invention. Theinvention is not limited to the embodiments depicted in the figures.

As understood by one of skill in the art, program code, as referred tothroughout this application, includes both software and hardware. Forexample, program code in certain embodiments of the present inventionincludes fixed function hardware, while other embodiments utilized asoftware-based implementation of the functionality described. Certainembodiments combine both types of program code. One example of programcode, also referred to as one or more programs, is depicted in FIG. 7 asprogram/utility 40, having a set (at least one) of program modules 42,may be stored in memory 28.

Embodiments of the present invention include a computer-implementedmethod, a computer program product, and a visual display device that: 1)obtain data indicating that a user perceives displayed text with atleast one character altered from the original text; 2) obtain textualelements (e.g., an image) of a visual display; 3) process the textualelements (e.g., by processing the image) to transform the content intonew content where the new content include pre-defined charactersubstitutions based on the at least one character altered from theoriginal text; and 3) displaying the new content so that when the userview the new content, the at least one character altered from theoriginal text is omitted from the new visual.

In many oral presentations given in professional, educational, andrecreational environments, the presenter relies upon visuals to assistin presenting the content in a comprehensive fashion. Often, thepresenter may utilize a projector coupled to a computing device or alarge monitor coupled to the device to project and share portions of thecontent with attendees. Visual aids can be helpful in comprehensivelypresenting the content of the presentation and can illustrate conceptsdiscussed as well as add additional information. For example, apresenter may display a slide with granular content on a given subject,while providing a quick overview, verbally. Thus, an individualattending the presentation, who is unable to correctly read the textdisplayed, will miss out on the content (and arguably the full impact)of the presentation. Certain individuals may experience cognitive issuesperceiving the displayed content because they do not perceive thecontent, and specifically, the characters and words, in the same manneras an individual who is not experiencing the cognitive issue. One commonissue in perceiving text, as written, is developmental dyslexia, whichis an issue that can cause an individual experiencing the issue toperceive words and letters in orders and configurations that do notappear in the text. Developmental dyslexia is often associated withvarious conditions, including but not limited to, dysgraphia, attentiondeficit hyperactivity disorder, auditory processing disorder,developmental coordination disorder, various developmental issues, andvarious sensory perception issues, including autism spectrum disorders.

The particulars of the manner in which a display of characters appearsdifferently to an individual experiencing a cognitive issue can bedetermined, based on the issue experienced. An individual who perceiveswords and characters differently will consistently perceive the wordsand characters in a consistent, though altered from the original text,manner. For example, in all visual displays, a given individual mayperceive the letter “d” as the letter “b” and/or an individual mayperceive the letter “W” as the letter “M.” Because the issuesexperienced by a given individual follow a discoverable pattern, once apattern is known, displayed text could be altered in order to generate avisual representation of the text that will be cognitively perceived bythe individual in the manner intended by the author of the text.

FIG. 1 demonstrates the consistency in the manner in which certainindividuals may perceive displayed content, as illustrated in FIG. 1,the textual elements which are substantive content of the displayedcontent in a manner that differs from the data comprising the actualdisplay. FIG. 1 depicts a presentation 100 where certain of theattendees may perceive the content of a visual display 110, projected bya projector 120, with certain, consistent, alterations. A firstindividual 125 among the individuals viewing the presentation, views thevisual display 110 in a manner characterized as a first altered display130. The first altered display 130 demonstrates that the firstindividual 125 visualizes the letter “E” when it appears in the visualdisplay 110 as the letter “B” and vice versa. Meanwhile, a secondindividual 135 views the visual display 110 in a manner characterized asthe second altered display 140. As depicted in FIG. 1, the secondaltered display 140 demonstrates that the second individual visualizesthe number “9” as the number “6” and vice versa. Thus, the perception ofthe visual display 110 by each individual corresponds to a particularvisual transformation of characters. The visual transformation of thecontent, for each individual, will be consistent across any visualdisplay 110.

Embodiments of the present invention include a computer-implementedmethod, a computer program product, and a system where one or moreprograms executed on one or more processing circuit obtain displayeddata, transform the content of the visual display in real-time (or closeto real-time), and re-display the data to the user such that the userwill perceive the intended content of the display, rather than thecontent, as visually impacted by cognitive issues that the user may ormay not be experiencing. As described in greater detail herein,embodiments of the present invention may include one or more of thefollowing aspects, which represent advantages over existing readingassistance technologies in presentation settings: 1) a computing device(e.g., a personal computing device, a wearable apparatus, a pencomputer, a smart device, an Internet of Things device, etc.) thatautomatically transforms displayed content to redisplay withmodifications; 2) voice-activated visual transformation controls; 3)network communication capabilities utilized to control visualtransformation; 4) rapid image processing by the computing device;and/or 5) virtual projection by the computing device of a resultantimage of the visual transformation; 6) any visual manipulation of anoriginal display can be experienced by a user of an embodiment of thepresent invention without altering the display itself or interferingwith the visual experience of other individuals viewing the display. Theenumerated aspects are discussed below.

First, some embodiments of the present invention include a computingdevice that automatically transforms displayed content and redisplays atleast a portion of the content, with modifications. The apparatus is anoptical display, which an individual can wear on his or her person(e.g., his or her head). This apparatus transforms displayed text, whichthe user does not perceive correctly, into content, in a format that theuser can read and comprehend. By wearing the optical display, the useris able to automatically obtain content that was previously, arguably,incomprehensible (or difficult to comprehend). The optical displayportion of embodiments of the present invention may comprise the programcode that automatically visually transforms displayed text in a dynamicmanner, such that different visual perception issues can beaccommodated. Other embodiments of the present information may house thevisual transformation code on a computing node that is accessible to thecomputing device.

Second, some embodiments of the present invention includevoice-activated visual transformation controls. In these embodiments, auser may take advantage of the dynamic nature of visual correction bymaking vocal commands, which are received by one or more programs, andutilized to adjust, dynamically, the visual transformation functionalityof the embodiment, to accommodate the specific visual perception issuesindicated by the user in the vocal command. For example, the user mayverbally indicate a pre-defined character error classification, whichcan include one or more of a vertical transformation of displayedcharacters, a horizontal transformation of displayed characters, and/ora visual similarity of displayed characters. Based on receiving a vocalcommand from the user indicating the pre-defined classification, the oneor more programs may automatically adjust the visual transformationsperformed by the one or more programs to address the specific issuesexperienced by this user. Although vocal commands can be utilized inembodiments of the present invention, as will be discussed later,embodiments of the present invention may include one or more programsthat determine an identity (and then, a perceived cognitive issue,experienced by a user) through various other methods, including but notlimited to using facial or other recognition techniques, based on theuser account or name logged into a computer system coupled to orinternal, to the device, or in any other manner.

Third, in addition to potentially adjusting visual display correctionbased on vocal commands, the computing device, in embodiments of thepresent invention, may include network communication capabilities,enabling one or more programs in an embodiment of the present inventionto obtain information regarding the specific visual perception issues ofa wearer of the apparatus, from another source. For example, based oncompleting a computerized test, one or more programs executing on thecomputing device upon which the test was administered may determine thathe user's visual perceptions issues fit a pre-defined classification.One or more programs in the computing device may obtain the pre-definedclassification of the user from the computing device, over a networkconnection, including the Internet. Based on the pre-definedclassification, the one or more programs adjust the types of visualtransformations performed by the apparatus.

Fourth, in some embodiments of the present invention, one or moreprograms either within the computing device or accessible to the programcode of the computing device obtain images of a display and rapidlyprocess the image to transform it into an image that includescorrections that address the visual perception issues of the wearer. Forexample, for a user who perceives the letter “E” as the letter “B” andvice versa, the one or more programs manipulates the image of a displaythat contains these letters and switches the location of these lettersin an image generated for the user.

Fifth, in some embodiments of the present invention, the one or moreprograms project a resultant image, generated based on an originaldisplay. The resultant image includes in it the visual changesimplemented in order to enable an individual with a visual perceptionissue to perceive a display in accordance with how the creator of thedisplay intended it to be perceived. For example, in FIG. 1, the firstindividual 125, and the second individual 135, rather than perceivingthe visual display 110 content as depicted in the first altered display130 and the second altered display 130, would view the content, based onthe projection, as it appears in the visual display 110.

FIG. 2 illustrates an example of a wearable apparatus 200 that comprisesan aspect of some embodiments of the present invention. As explainedabove, a computing device utilized in embodiments of the presentinvention may include a wearable device. The apparatus 200 of FIG. 2,which is just one example of a computing device that may comprise one ormore aspects of some embodiments of the present invention, is an opticalhead mounted display (OHMD). As will be discussed in greater detail, theOHMD apparatus 200 in some embodiments of the present invention includesa camera 220, a processing unit 210 for image processing, a projector,such as a prism 250, and a microphone 230. The configuration of elementsin the apparatus 200 are merely one example of possible configurations(and elements) that may be utilized to achieve the describedfunctionality in embodiments of the present invention. This example isoffered for illustrative purposes only.

As understood by one of skill in the art, other computing devices, forexample, those that are neither wearable not head-mounted, may beutilized in embodiments of the present invention, in place of ortogether with the OHMD apparatus 200. As will be discussed later, insome embodiments of the present invention, the device that projectscorrected text may include a computing device, such as a pen computerand any Internet of Things device (e.g., a smart device).

As will explained utilizing an OHMD apparatus 200 as an example,computing devices utilized in embodiments of the present invention mayinclude devices capable of receiving input regarding: 1) the specificcognitive issues of a user; and 2) visual displays being viewed by theuser and based on these inputs. Based on this input, these devices arecapable of projecting and/or otherwise displaying a version of thetextual content of the visual displays in a manner that enables the userto experience this content without the cognitive issues influencing theuser's perception of the content.

Returning to FIG. 2, in an embodiment of the present invention, thewearable apparatus 200, for example, one or more processors embodied inthe wearable apparatus 200, as a central processing unit (CPU) 210,obtain information regarding the cognitive issues experienced by thewearer, that result in the wearer perceiving displayed text in analtered manner, when compared to the original content (displayedcontent). As understood by one of skill in the art, various cognitiveissues can fit known patterns and thus, a specific impairment can beassigned a “level” and that level refers to one or more specificcognitive issues. For example, a user with a cognitive issue categorizedas a given level (e.g., “level 1”) may view certain characters reversedvertically (e.g., a “6” as a “9”, and vice versa, and an “M” as a “W”and vice versa). Thus, one or more processors (e.g., CPU 210) in theapparatus 200 (or accessible to the apparatus 200) may receive datadescribing a cognitive challenge of a wearer as a level and the one ormore processors may interpret this level to refer to a specificcognitive issue, requiring specific adjustments in order to display textto this wearer, such that the text appears to the wearer unaltered bythe cognitive issue experienced by the wearer. One or more programsexecuting on the apparatus may receive information regarding thecognitive challenges of a wearer over a communications connection, froma computing node communicatively connected to the apparatus, forexample, over a wireless connection, such as the Internet.

In some embodiments of the present invention, the one or more programsexecuting on a processor in the apparatus 200 receive data regarding thecognitive issues of the wearer from a vocal command. The apparatus 200includes speakers 240, which may prompt the wearer to can give thiscommand, which the one or more programs may receive and interpret, inorder to adjust displayed text in a manner that will accommodate thewearer. For example, after a prompt from the speakers 240, the wearermay speak an identifier, such as a level identifier, into a microphone230 in the apparatus 200. Program code executed by the CPU 210 receivesand interprets the vocal command obtained via the microphone 230. Insome embodiments of the present invention, the one or more programs mayutilize an alternative recognition method (technology or technique) toidentify the user and determine, based on the identity of the user, thecognitive issues experienced by the user. For example, embodiments ofthe present invention may include facial or other physical recognitiontechniques (e.g., fingerprint), that determine the identity of a userbased on a physical feature. One or more programs in some embodiments ofthe present invention may determine the identity of a user based onaccessing user information from interactions of the user with theapparatus or with an input device communicatively couples to theapparatus. For example, in some embodiments of the present invention,the one or more programs may identify a user based on a user account orname on a computer system communicating with and/or internal to, theapparatus.

In some embodiments of the present invention, the apparatus 200 alsoincludes a camera 220, which may include functionality for both videoand still images. The camera 220 captures original images (and video)that includes text and provides this content to one or more programsexecuted by the CPU 210, which can process the captured images. The oneor more programs process the images by identifying text (e.g.,characters), that the wearer will perceive differently than displayed,based on the cognitive issues previously provided to the program code.The one or more programs alter the images (e.g., by creating an overlayof certain portions of the image) such that when projected by theapparatus 200, for example, utilizing the prism 250, the wearer of theapparatus 200 will view the original content of the text, while wearingthe apparatus 200, rather than the altered content she or he would viewwithout wearing the apparatus 200. In some embodiments of the presentinvention, the program code utilizes the prism 250 in the apparatus 200to overlay specific changes to the original images that enable thewearer to experience the original content (text) included in theseimages. The program code determines the changes to include in theoverlay based on the cognitive issues of the wearer.

FIG. 3 is a workflow 300 that depicts the utilization of the apparatus200 of FIG. 2 by a wearer, in accordance with certain aspects of anembodiment of the present invention. In an embodiment of the presentinvention, a user will wear the OHMD device (e.g., FIG. 2, apparatus200) (310). One or more programs executing on a processing unit of theOHMD device (e.g., FIG. 2, CPU 210), receive data indicating cognitiveissues experienced by the wearer when the wearer reads displayed text(320). In an embodiment of the present invention, the user may providethe apparatus 200 (FIG. 2) with this information via a voice command.The user may indicate the issue by identifying a cognitive issuesutilizing a pre-defined level identifier. For example, when the programcode of the apparatus 200 (FIG. 2) receives a vocal command of “Level1”, the one or more programs may determine that this command indicatesthat the wearer perceives the character “E” as “B” and vice versa. Insome embodiments of the present invention, rather than receiveinformation related to cognitive issues of the user via a storedpersonal profile on a memory that is part of the device and/oraccessible to the program code executing on the CPU 210 (FIG. 2) of thedevice. For example, the apparatus 200 (FIG. 2) may be capable ofcommunicating over Bluetooth and/or other wireless communicationstandards to retrieve information related to the user and the cognitiveissues that are relevant to the user. In some embodiments of the presentinvention, one or more programs may query an accessible data source(such as a computing node of a distributed network) in order to obtaininformation related cognitive issues experienced by a given user. Theuser may supply identifying information that will enable the one or moreprograms to make this query.

In an embodiment of the present invention, based on obtaining the dataindicating cognitive issues experienced by the wearer when the wearerreads displayed text, one or more programs executing on a processingunit (e.g., FIG. 2, CPU 210) of the OHMD device (e.g., FIG. 2, apparatus200) utilize an image capture device (e.g., FIG. 2, camera 220) tocontinuously capture (e.g., in real-time) displayed images (330). Basedon the data indicating cognitive issues experienced by the wearer, theone or more programs convert the images captured such that the resultantimages include the content of the original image (e.g., the text in theoriginal images) with adjustments made to enable the wearer to see theimages without the cognitive issues of the wearer influencing thedisplayed images (340). For example, if a wearer views the resultantimages, the user will view the original textual content. Without the oneor more programs transforming the images, the user would not be able toview the original textual content because the cognitive issues of theuser would affect the user's perception of the display. The one or moreprograms virtually display the resultant images to the wearer (350). Inan embodiment of the present invention, the one or more programs utilizea projector in the OMHD device to display the transformed content.

FIG. 4 is an illustration of a meeting 400 in which two attendees 437438 of the meeting are utilizing OMHD devices 452 454 (e.g., FIG. 2apparatus 200) to view displayed content 410. One or more programsexecuted by processing units in the OMHD devices 452 454 display thedisplayed content 410 as transformed displays 472 474. Each transformeddisplay includes text changes from the displayed content 410 that allowthe wearer of each OMHD devices 452 454 to perceive the text in thedisplayed content 410 as being identical to the text of the displayedcontent 410. However, the in order to accommodate the cognitive issuesexperienced by the attendees 437 438, the one or more programs areutilizing a projectors in the OHMD devices 452 454 to project the textwith differences from the original in the displayed content 410. Thetransformed displays 472 474 by the OHMD devices 452 454 include changesto the characters in the displayed content 410. However, the attendees437 438 perceive the transformed displays 472 474 as the virtualdisplays 462 464.

Referring to FIG. 4, a first attendee 437 perceives the character “E” as“B” and vice versa. As illustrated in FIG. 3, one or more programs in anembodiment of the present invention obtains this information regardingthis individuals' cognitive issues. Thus, to correctly read thedisplayed content 410, which includes the text “HONEY BEE IS ANY BEENUMBER OF GENUS APIS NUMBER: 0123456789” the one or more programs of theOHMD device 452 worn by this first attendee 437 displays the text of thedisplayed content 410 as a first transformed display 472, which includesthe text: “HONBY EBB IS ANY EBB NUMEBR OF GBNUS APIS NUMEBR:0123456789.” However, the first attendee 437 views the first transformeddisplay 472 as the first virtual display 462, which includes the text:“HONEY BEE IS ANY BEE NUMBER OF GENUS APIS NUMBER: 0123456789.”

A second attendee 438 perceives the character “M” as “W” and vice versaand the character “6” as “9” and vice versa. As illustrated in FIG. 3,one or more programs in an embodiment of the present invention obtainsthis information, for example, via a voice command. This information maybe conveyed by utilizing a pre-defined level to characterize theseissues. To enable the second attendee 438 to read the displayed content410, which includes the text “HONEY BEE IS ANY BEE NUMBER OF GENUS APISNUMBER: 0123456789” the one or more programs of the OHMD device 454 wornby this second attendee 438 displays the text of the displayed content410 as a second transformed display 474, which includes the text: “HONEYBEE IS ANY BEE NUMBER OF GENUS APIS NUMBER: 0123459786.” However, thesecond attendee 438 views the second transformed display 474 as thesecond virtual display 464, which includes the text: “HONEY BEE IS ANYBEE NUMBER OF GENUS APIS NUMBER: 0123456789.”

Although FIG. 4 uses OMHD devices 452 454 as illustrative examples ofcomputing devices that incorporate aspects of embodiments of the presentinvention, as understood by one of skill in the art, a computing deviceused to project new content, based on processed original content, to auser, may include various other computing devices. Some example ofdevices that can be utilized in embodiments of the present inventioninclude, but are not limited to, a pen computer, a personal computingdevice, a smart device, an and Internet of Things device. In embodimentsof the present invention, these devices obtain original content, processthe content, and project at least a portion of the resultant processedcontent to a user.

FIG. 5 is a workflow 500 that illustrates the functionality of certainembodiments of the present invention in a particular setting, in thisexample, in a group meeting. To illustrate how aspects of embodiments ofthe present invention fit into the framework of a group meeting andassist the individuals attending the meeting is accessing the content ofvisuals utilized during the meeting, certain of the aspects describedrelate to the behaviors of the individuals, while other aspects relateto aspects of embodiments of the present invention.

The workflow 500 of FIG. 5 commences with individuals attending ameeting in a conference room (510). During the presentation, textualcontent appears on a visual display, including but not limited to ascreen and/or a monitor (520). The individuals in the conference roomare able to see this visual display. One or more programs in anembodiment of the present invention determine if any individualsattending the meeting have cognitive issues that would create perceptionissues related to perceiving the content (530). Based on identifying anindividual with a cognitive issue, the one or more programs identify theissue and determine one or more changes to implement to the content toenable the individual to view the content as it appears in the absenceof the identified issue (540). The one or more programs capture thecontent as an image (550). The one or more programs transform the imageby generating a new image that includes the one or more changes in thecontent (560). The one or more programs display the new image to theuser (570).

As discussed earlier, the manner in which the one or more programsdisplays the new image to the user may vary. For example, the one ormore programs may display the new image at a position in which it isvisually overlaid on displayed image. The one or more programs maydisplay the new image such that it appears to the individual as avirtual display. However, in embodiments of the present invention, theone or more programs display the new image to the individual in a mannerthat does not affect the perception of the original content by theremaining individuals in the meeting.

In embodiments of the present invention, the one or more programscapture, convert, and display, the image to an individual at a paceclose to real-time. The capture, transformation, and re-display oftextual content occurs quickly in part because embodiments of thepresent invention utilized pre-defined classifications to identify whatchanges should be made to an image before it is displayed.

While embodiments of the present invention are useful in convertingoriginal content for re-projection and viewing by an individual withcognitive perception challenges, aspects of some embodiments of thepresent invention may also be utilized to assist a user withoutcognitive perception challenges read content that is generated by anindividual with cognitive perception challenges. For example, anindividual (with cognitive perception challenges) may prepare apresentation that=contains displayed text with consistent charactererrors. In this case, the user (without cognitive perception challenges)will perceive the text with consistent character differences from thedisplayed text, because the individual, who prepared the text, and theuser, who is perceiving the text, each perceive characters differently.Thus, whether it is the display that contains character differences,such as consistently switching a first character for a second character,or consistently inverting one or more characters, or the user whoperceives these differences, when viewing an original display, aspectsof some embodiments of the present invention may assist both theindividual and the user in perceiving substantially similar content.FIG. 6 is a workflow 600 of an embodiment of the present invention whichis applicable in both scenarios.

Referring to FIG. 6, one or more programs in some embodiments of thepresent invention one or more programs determine if a user of a visualdisplay apparatus (that includes an image capture device, and aprojection device communicatively coupled to the one or more processorsexecuting the one or more programs) perceives displayed text on a visualdisplay with consistent character differences (610). The one or moreprograms makes this determination based either on obtaining dataindicating that the user perceives displayed text with consistentcharacter differences or by determining that text on the visual displayinclude consistent character differences. As discussed above, the usercould be perceiving the text differently than it appears in the displayor the user could be perceiving the text, as displayed, but the textincludes consistent character differences. Based on the determination,the one or more programs obtain, from the image capture device, an imageof the visual display (which is within a visual range of the imagecapture device) (620). Based on the determination, the one or moreprograms process the image to generate a new image (630).

In some embodiments of the present invention, the one or more programsprocess the image by transforming the image into the new image; the newimage includes textual elements with pre-defined character substitutionsbased on the consistent character differences. In the case where theuser text in the visual display objectively contained consistentcharacter differences, the new image would contain text that does notinclude these differences. For example, if an objective observer wouldhave perceived the visual display as containing a character that wasdisplayed at an orientation that differs from the remaining text, thenew image would include the text, including the character, all with thesame orientation. Alternatively, if the user of the visual displayapparatus perceived the original visual display with consistentcharacter differences, for example that were not present from thepoint-of-view of the creator of the visual, the new image would includetextual elements with pre-defined character substitutions based on theseconsistent character differences.

Returning to FIG. 6, upon generating the new image, the one or moreprograms display (e.g., via the projection device), the new image, tothe user, (640) where based on viewing the new image, the user views thetextual elements without the consistent character differences (whetherthose difference were part of the original display or just presentbecause of the cognitive issues of the user perceiving the originaldisplay). Depending on the type of device, the display could beprojected onto a screen, projected within the line of sight of the user,and/or display on a screen on a computing device accessible (or part of)the visual display apparatus.

Embodiments of the present invention include a computer-implementedmethod, a computer program product, and a visual display apparatus whereone or more programs executed by one or more processors obtains dataindicating that a user of a/the visual display apparatus (which includesan image capture device and a projection device communicatively coupledto the one or more processors) perceives displayed text with consistentcharacter differences. The one or more programs obtain, from the imagecapture device, an image of the visual display within a visual range ofthe image capture device wherein the image comprises textual elements.Based on the data, the one or more programs process the image togenerate a new image; the processing includes transforming the imageinto the new image where the new image includes the textual elementswith pre-defined character substitutions, based on the consistentcharacter differences.

Cloud computing is a model of service delivery for enabling convenient,on-demand network access to a shared pool of configurable computingresources (e.g., networks, network bandwidth, servers, processing,memory, storage, applications, virtual machines, and services) that canbe rapidly provisioned and released with minimal management effort orinteraction with a provider of the service. This cloud model may includeat least five characteristics, at least three service models, and atleast four deployment models.

Characteristics are as follows:

On-demand self-service: a cloud consumer can unilaterally provisioncomputing capabilities, such as server time and network storage, asneeded automatically without requiring human interaction with theservice's provider.

Broad network access: capabilities are available over a network andaccessed through standard mechanisms that promote use by heterogeneousthin or thick client platforms (e.g., mobile phones, laptops, and PDAs).Resource pooling: the provider's computing resources are pooled to servemultiple consumers using a multi-tenant model, with different physicaland virtual resources dynamically assigned and reassigned according todemand. There is a sense of location independence in that the consumergenerally has no control or knowledge over the exact location of theprovided resources but may be able to specify location at a higher levelof abstraction (e.g., country, state, or datacenter). Rapid elasticity:capabilities can be rapidly and elastically provisioned, in some casesautomatically, to quickly scale out and rapidly released to quicklyscale in. To the consumer, the capabilities available for provisioningoften appear to be unlimited and can be purchased in any quantity at anytime.

Measured service: cloud systems automatically control and optimizeresource use by leveraging a metering capability at some level ofabstraction appropriate to the type of service (e.g., storage,processing, bandwidth, and active user accounts). Resource usage can bemonitored, controlled, and reported, providing transparency for both theprovider and consumer of the utilized service.

Service Models are as follows:

Software as a Service (SaaS): the capability provided to the consumer isto use the provider's applications running on a cloud infrastructure.The applications are accessible from various client devices through athin client interface such as a web browser (e.g., web-based e-mail).The consumer does not manage or control the underlying cloudinfrastructure including network, servers, operating systems, storage,or even individual application capabilities, with the possible exceptionof limited user specific application configuration settings.

Platform as a Service (PaaS): the capability provided to the consumer isto deploy onto the cloud infrastructure consumer-created or acquiredapplications created using programming languages and tools supported bythe provider. The consumer does not manage or control the underlyingcloud infrastructure including networks, servers, operating systems, orstorage, but has control over the deployed applications and possiblyapplication hosting environment configurations.

Infrastructure as a Service (IaaS): the capability provided to theconsumer is to provision processing, storage, networks, and otherfundamental computing resources where the consumer is able to deploy andrun arbitrary software, which can include operating systems andapplications. The consumer does not manage or control the underlyingcloud infrastructure but has control over operating systems, storage,deployed applications, and possibly limited control of select networkingcomponents (e.g., host firewalls).

Deployment Models are as follows:

Private cloud: the cloud infrastructure is operated solely for anorganization. It may be managed by the organization or a third party andmay exist on-premises or off premises.

Community cloud: the cloud infrastructure is shared by severalorganizations and supports a specific community that has shared concerns(e.g., mission, security requirements, policy, and complianceconsiderations). It may be managed by the organizations or a third partyand may exist on-premises or off-premises.

Public cloud: the cloud infrastructure is made available to the generalpublic or a large industry group and is owned by an organization sellingcloud services.

Hybrid cloud: the cloud infrastructure is a composition of two or moreclouds (private, community, or public) that remain unique entities butare bound together by standardized or proprietary technology thatenables data and application portability (e.g., cloud bursting forload-balancing between clouds).

A cloud computing environment is service oriented with a focus onstatelessness, low coupling, modularity, and semantic interoperability.At the heart of cloud computing is an infrastructure that includes anetwork of interconnected nodes.

Nodes 10 maycommunicate with one another. They may be grouped (not shown) physicallyor virtually, in one or more networks, such as Private, Community,Public, or Hybrid clouds as described hereinabove, or a combinationthereof. This allows cloud computing environment 50 to offerinfrastructure, platforms and/or software as services for which a cloudconsumer does not need to maintain resources on a local computingdevice. It is understood that the types of computing devices 54A-N shownin FIG. 8 are intended to be illustrative only and that computing nodes10 and cloud computing environment 50 can communicate with any type ofcomputerized device over any type of network and/or network addressableconnection (e.g., using a web browser).
